Claims

1. A structure for adjusting the height of a handle bar on a scrubber, characterized in that, The system includes an outer rod (1) that is connected to the main body of the floor scrubber and an inner rod (2) that moves up and down along the outer rod (1). The outer rod (1) has at least two gear holes (3) inside. The inner rod (2) is connected to a ball bearing (4) that is adapted to the gear hole (3). The inner rod (2) has a push rod (5) that moves up and down along the inner rod (2) inside. The upper end of the push rod (5) is connected to a button (6). The lower end of the push rod (5) drives the ball bearing (4) to move radially along the outer rod (1). The ball bearing (4) engages with the gear hole (3) to limit the inner rod (2).

2. The structure for adjusting the height of the handle bar on the scrubber-dryer according to claim 1, wherein, The jumping ball (4) includes a driving part (41) and a contact part (42). The driving part (41) and the contact part (42) are fixedly connected. When the push rod (5) moves downward, it touches the driving part (41) and the contact part (42) moves away from the gear hole (3). When the push rod (5) moves upward, it moves away from the driving part (41) and the contact part (42) moves closer to the gear hole (3).

3. The structure for adjusting the height of the handle bar on the scrubber-dryer according to claim 2, characterized in that, The part of the drive unit (41) that contacts the push rod (5) is a downwardly inclined first slope (43), and the lower end of the push rod (5) has a second slope (51) that is adapted to the first slope (43).

4. The structure for adjusting the height of the handle bar on the scrubber-dryer according to claim 2, wherein, The jumping ball (4) is connected to a first elastic element for driving the jumping ball (4) to move away from the gear hole (3). One end of the first elastic element is connected to the inner rod (2), and the other end of the first elastic element is connected to the driving part (41) of the jumping ball (4).

5. The structure for adjusting the height of the handle bar on the scrubber-dryer according to claim 4, wherein, The button (6) is connected to a second elastic element for driving the button (6) to reset. One end of the second elastic element is connected to the button (6), and the other end of the second elastic element is connected to the inner rod (2).

6. The structure for adjusting the height of the handle bar on the walk-behind scrubber of claim 1, wherein, The inner wall of the outer rod (1) is provided with a first limiting part (11) to prevent the inner rod (2) from fully extending out of the outer rod (1). The outer wall of the inner rod (2) is provided with a second limiting part (21) that is adapted to the first limiting part (11). When the jumping ball (4) is located in the uppermost stop hole (3), the first limiting part (11) abuts against the second limiting part (21).

7. The structure for adjusting the height of the handle bar on the scrubber-dryer according to claim 5, wherein, The first elastic element and the second elastic element are springs.

8. The structure for adjusting the height of the handle on a floor scrubber according to claim 1, characterized in that, The upper end of the inner rod (2) is provided with a handle (22) for hand gripping.
